  2. 2. Micromechanical Modelling of Wood and Fibre Properties

    University dissertation from Division of Structural Mechanics, Lund Institute of Technology

    Author : Kent Persson; Lund University.; Lunds universitet.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Byggnadsteknik; Building construction; Microfibril angle; Density; Hygroexpansion; Stiffness; Simulation; Wood; Fibre; pollution control; Miljöteknik; kontroll av utsläpp; Material technology; Materiallära; materialteknik;

    Abstract : Wood is a material with mechanical properties that vary markedly, both within a tree and among trees. Moisture changes lead to shrinkage or swelling and modify the mechanical properties. READ MORE

  3. 3. Manufacture of long-fibre reinforced ceramics by reaction bonding

    University dissertation from Division of Structural Mechanics, Lund Institute of Technology

    University dissertation from Stockholm : KTH

    Author : Stefan Antonsson; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignin; xylan; kraftliner pulp; mechano-sorptive creep; hygroexpansion; stiffness; fibre shape; fibre width; lignin; xylan; kraftlinermassa; mekanosorptivt kryp; hygroexpansion; styvhet; fiberform; fiberbredd; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Cellulose and paper engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Cellulosa- och pappersteknik;

    Abstract : A large part of the world paper manufacturing consists of production of corrugated board components, kraftliner and fluting, that are used in many different types of corrugated boxes. Because these boxes are stored and transported, they are often subjected to changes in relative humidity. READ MORE
